The basic function of the spring washer is to give a force to the nut after the nut is tightened, increasing the friction between the nut and the bolt!It is a protective measure to prevent the loosening of the fastening bolts caused by the vibration of the equipment in operation.
The anti-loosening principle of the spring washer is that after the spring washer is flattened, the spring washer will generate a continuous elastic force, so that the threaded connection of the nut and the bolt will continue to maintain a frictional force and generate a resistance torque, thereby preventing the nut from loosening.At the same time, the sharp corners at the opening of the spring washer are respectively embedded into the surface of the bolt and the connected part, thereby preventing the bolt from rotating relative to the connected part.
